Answer:

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

Explanation:

  • For the equilibrium system:

<em>X₂ + Y₂ ⇄ 2XY,</em>

The no. of moles of gases in each side is constant; there is 2 moles of gases at reactants side and 2 moles of gases at products side.

So, changing the volume will not affect on the equilibrium system.

<em>So, the right choice is:</em>

3) The relative concentrations of each gas must remain constant.

4)The concentration of each gas will not change.

The chemical formula for glucose (sugar) is C6H12O6. What are the individual numbers called in a chemical formula?
givi [52]

The individual numbers which are present in chemical formula is subscript.

<h3>What is chemical formula?</h3>

Chemical formula of any compound of chemistry consist more than one atoms in it and gives idea about the number of atoms present in that compound.

Given chemical formula of glucose is C₆H₁₂O₆.

In the given chemical formula of glucose, number which shows the amount of carbon, hydrogen and oxygen are known as subscripts.

Hence, individual number are subscript.

Summarize your findings in a short report of 150 words. Include your hypothesis, observations, data, calculations, and conclusio
Damm [24]

Answer:

Follow these steps.

1. Fill the matchbox with pebbles. Weigh the matchbox with the pebbles inside. Record that weight.

2. Tie the string to the box. Allow the string to hang over the edge of the table.

3. Tie the other end of the string to a corner of the plastic bag, leaving an opening to put in coins.

4. Add coins one by one until the box is pulled off the table.

5. Count and record the number of coins and the weight of the bag with the coins in it.

6. Lay the round sticks on the table about 1 inch apart and about 2 inches from the edge of the table.

7. Put the matchbox on the rollers farthest from the edge of the table.

8. Now add coins one by one to the bag until the box is pulled off the table.

9. Count and record the number of coins and the weight of the bag with the coins in it.

10. Repeat the experiment. Determine your margin of error if your results vary. For accuracy, repeat the experiment if desired.

11. Using the equation for the coefficient of friction in the text above, determine the coefficient of friction for the matchbox in each experiment. Include this data in your summary.

A reaction between liquid reactants takes place at −10.0°C in a sealed, evacuated vessel with a measured volume of 45.0L. Measur
maks197457 [2]

Answer: 0.0624 atm

Explanation:-

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = ?

V= Volume of the gas = 45.0 L

T= Temperature of the gas = -10.0°C = 263 K    0^00C=273K

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas

Moles of gas=\frac{\text{ given mass}}{\text{ molar mass}}= \frac{19.0g}{146g/mole}=0.130moles

P=\frac{nRT}{V}=\frac{0.130\times 0.0821\times 263}{45.0}=0.0624atm

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
